ADELBERT A. DAILEY, OF VINAL HAVEN, MAINE.

HOOP-SHAVING MACHINE Application filed June 24, 1907.

T 0 all whom it may concern:

Be it known that I, ADELBERT A. DAILEY, a citizen of the United States,and a resident of Vinal Haven, in the county of Knox and State of Maine,have invented an Improvement in Hoop-Shaving Machines, of which thefollowing description, in connection with the accompanying drawing, is aspecification, like letters on the drawing representing like parts.

This invention relates to a machine designed primarily for the shavingor planing of saplings in the manufacture of barrel hoops but which isuseful for any other similar purpose.

The invention resides in a machine in which the rotating cutter frame ismounted at one end of a supporting frame, and in which a carriagetravels back and forth toward and away from the cutter frame to draw thework through the cutter together with various devices securing theautomatic action in various of its movements.

The nature of the invention will best appear from the accompanyingdescription and the drawings and will be particularly pointed out in theappended claims.

The drawings represent a machine embodying the invention in itspreferred form.

Figure 1 is a side elevation of the upper portion of the machine partlywith the central portion broken away and with the cut ter frame partlyin cross section; Fig. 2 is .a top plan view of the machine with thecentral portion broken away.

The machine comprises a suitable support ing frame, the legs of whichare represented at A. A trackway upon which the gripping device to bedescribed travels extends substantially throughout the length of themachine, and is herein shown as formed of two angle irons B, B,extending from one pair of legs, A, A, to the other and connecting thesame to form the rigid frame. These angle irons serve themselves as therails of the trackway.

The cutter ward end of the machine and is bolted in place by the bolts0. The cutter C is of the rotary type comprising in the form shown twocutting blades C and is mounted on a shaft C which is driven by thepulley C from any suitable source of power. The work is held up againstthe cutter by a series of yieldingly-mounted bed rolls D. These rollsare all mounted on the support D frame C is located at the for-Specification of Letters Patent.

path of the cutter frame by means of a set screw and check nut. Eachroll D is yieldingly mounted upon the support I) by means of the springsD A guide bar E is mounted in the cutter frame in the rear of the cutterand its lower edge is adjusted to the same height as the lowest point ofthe path of the cutter.

The adjustment of the support D enables work of varying thicknesses tobe passed through the cutter frame and determines the amount to beremoved by the cutter.

The provision for the independent yielding of each of the bed rolls Denables work of irregular form or of imperfect character, such forexample as the knotted or irregular side of the sapling to pass throughthe cutter, each bed roll yielding one after the other for that purpose.7

The springs holding the bed rolls up to the work are of sufficientstrength that any two of them will hold the work up into cuttingposition.

A pair of guide or directing rolls F are mounted in front of the cutterand the bed rolls and are each yieldingly pressed toward the other bymeans of the springs F. The upper roll is set slightly in the rear ofthe lower so that when the work is guided in beneath the cutter it willbe pressed downwardly against the bed roll and its passage beneath theguide bar E assured.

The work is drawn through the cutter frame by means of a gripping devicemounted on a carriage which travels back and forth toward and away fromthe cutter head upon the trackway B. This carriage is shown at G ascomprising a truck provided .with four wheels g running on the rails B.

The truck G carries the gripping device shown as a pair of oppositelydisposed gripping jaws H pivoted with respect to each other at 71 andnormally held closed by the spring H pressing against the longer arms ofthe jaws. A latch H is pivoted upon one of the jaws and provided with anotch h adapted to engage with and hold pressed the other jaw againstthe action of the spring H. A plunger H is mounted to extend between thegripping end of the jaws and to contact or be connected with the latch Hand is normally held in its forward position by a spring 7b. This spring72 when the plunger is connected to the latch will serve to cause whichis adjustable toward and from the the notch kg of the latch to engagethe pivv draw the work past the cutter by means of a rope or chain Lwhich is wound up on the sleeve M by means of a pulley N which is drivenby any suitable motor. The sleeve M is loosely mounted upon the shaft Nof the pulley and is connected thereto to be driven thereby by asuitable clutch mechanism, herein shown as a sleeve splined upon theshaft N and moved so that its lugs n engage "the corresponding lugs 71,on the sleeve M of its rearward movement.

by means of the rod 0. The rod 0 extends to the forward end of themachine and is provided with a suitable operating handle 0 so that whenthe handle O is turned the clutch is operated to cause the sleeve M tobe connected with and driven by the shaft N. When the rod is turned inthe opposite direction the clutch will be released allowing the sleeve Mto turn freely on the shaft N.

The releasing of the clutch is secured automatically by providing therod 0 with a depending lug 0 adapted to be struck by a cam projection Hon one side of the carriage when the carriage reaches the desired limitThe gripping jaws upon the carriage are also opened automatically torelease the work after it is drawn through the cutter-head and beforethe return movement of the carriage begins by means of rolls P mountedupon the frame of the machine and in the path of movement of the uppergripper jaw. As the carriage carries the gripper jaws beneath the rollsP they act by reason of the inclination of the jaw to depress the upperjaw and release the work. The spring plunger 151 then acts to push thework out from between the jaws so that it may drop btween the rails Bonto the floor, and upon the continued movement of the carriage thelatch H catches and holds the jaws open.

From the foregoing description of the machine its operation will beobvious. The work is directed in between the guide rolls F beneath thecutter and guide and over the bed rolls which are properly adjusted, andthen it is forced in between the gripper jaws which are at that timeheld open by the latch. The work pushes back the plunger H releasing thelatch, causing the jaws to grip the work, and the operator then turnsthe handle 0 locking the clutch N and the carriage is thereby movedbackwardly by j the power applied to the pulley N until the work isdrawn through the cutter head. The rolls P open the jaws, the plunger Hpushes the work out from the jaws and it falls on the floor andimmediately thereafter the cam H acting on lug O releases the clutch andthe weight K at once acts to return the carriage to its forwardposition.
